Zhang, Zhe,Wang, Feng,Wang, Min,Xu, Shutao,Chen, Haijun,Zhang, Chaofeng,Xu, Jie
, p. 2523 - 2527 (2014)
We here demonstrate a simple, efficient and eco-friendly protocol for the direct synthesis of imines from amines via a facile α-MnO2 catalyzed-procedure at rt. Up to 13 benzylic, heterocyclic, and normal aliphatic imines were synthesized with 95-99% selectivity at 82-99% conversion. the Partner Organisations 2014.

In this study, we report the synthesis of a metal-free truxene-based conjugated microporous polymer (Tx-CMP) and demonstrate its heterogeneous photocatalytic applications under direct sunlight. We employed Tx-CMP for the oxidative homocoupling of amines.

Developing new photocatalysts for settling the tightest bottlenecks that lower efficiency, inferior selectivity and harsh conditions in organic oxidation reactions with air is very significant. Herein, ZnW–DPNDI–PYI was achieved by assembling a functional photosensitizer, an oxidation catalyst [BW12O40]5?, and an organocatalyst into one single framework. The anion?π and N–H?O hydrogen bonds interactions facilitate the consecutive photo-induced electron transfer (conPET) process for the photocatalytic oxidation by stabilizing the radical-anion intermediate and catalyst-substrate interacted moiety. Besides, N,N′-bis(4-pyridylmethyl)naphthalene diimide (DPNDI) can be excited by visible light, the photogenerated electron and hole would further activate oxygen and substrates, respectively, to give the corresponding redox products. High conversion and selectivity of ZnW–DPNDI–PYI in photocatalytic coupling of primary amines and olefins epoxidation with air under visible-light have been demonstrated.
Ultrathin HNb3O8 nanosheets with oxygen vacancies for enhanced photocatalytic oxidation of amines under visible light irradiation
Chen, Junli,Wang, Hai,Zhang, Zhiqiang,Han, Lifeng,Zhang, Yonghui,Gong, Feilong,Xie, Kefeng,Xu, Liancai,Song, Wei,Wu, Shide
, p. 5493 - 5503 (2019)
Ultrathin HNb3O8 nanosheets (HNb3O8 NSs) with oxygen vacancies were successfully synthesized by a simple bottom-up hydrothermal process. The obtained nanosheets were uniform with a thickness of about 3.02 nm and

Treatment of a mixture of dibenzothiophene dioxides and benzaldehyde N-benzylimines with potassium hexamethyldisilazide induces sequential intermolecular and intramolecular SNAr reactions to eventually form the corresponding 5H-dibenzo[c,e]azep
Ball-Milling Induced Debonding of Surface Atoms from Metal Bulk for Construing High-Performance Dual-Site Single-Atom Catalysts

One of the most pressing challenges in single-atom catalysis is the manipulation of the coordination environment of central metals to maximize the catalyst performance. Herein, we fabricated a high-performance catalyst (Co-SNC) by introducing S into the n
